Just coated my bed in Herculiner, and have a bunch left over. I want to coat my bedrails too, but don't want to have as as much of the roughness that my bed . I was thinking of using rustoleum spray coating to do the rails, so it turns out smoother.

My question was, has anyone ever used the rustoleum coating? I want something that's going to last a while, not just chip after a year.
Anyone had experience with the Rustoleum coating?
